$$What forecasters said that day
The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Raleigh, NC wrote its last area forecast discussion before this river flood warning went out at Feb 6, 7:23 AM EST, 4 hours 53 minutes earlier.
Area forecast discussion, Feb 6, 7:23 AM EST, 4 hours 53 minutes before
AREA FORECAST DISCUSSION National Weather Service Raleigh NC 723 AM EST Thu Feb 6 2020 .SYNOPSIS... A front over northern NC this morning will drift northward and become quasi-stationary from northwestern NC to central VA through this afternoon, ahead of a strong area of low pressure and trailing cold front that will track across the Carolinas late this afternoon and early tonight. A secondary cold front will follow and cross the region Friday morning. && .NEAR TERM /THROUGH TONIGHT/... As of 540 AM Thursday... ...Multi-faceted hazard risks include flooding, severe storms, and strong to damaging gradient winds/gusts both in a growing warm sector this afternoon and again in post-frontal CAA/strong MSL pressure rises Friday morning... Downstream of a blocking ridge over the ern Pacific, the nrn and srn branches of the upr jet have phased from nrn Mexico to the lwr Great Lakes. Within the associated phased, full latitude trough from the nrn Plains to nrn Mexico this morning, several notable shortwave perturbations are evident in wv satellite and 00Z/Thu upr air data from the lwr MS Valley wnwwd across the srn and cntl (high) Plains. The lead two of these features over the lwr MS Valley wwd to ern OK this morning will shear rapidly newd with associated upr divergence maxima and forcing for ascent that will focus from the TN Valley newd across the srn Appalachians this morning. Meanwhile, the strongest of these shortwave perturbations, and most influential for cntl NC, were still digging into the longwave trough base this morning and located over ern CO and wrn TX/the Rio Grande, respectively. These features are forecast to laterally interact and be drawn nearer while pivoting newd across the TN Valley and srn Appalachians through 12Z Fri, with associated extreme mid level height falls forecast to maximize between 200-250 meters over wrn NC through that time, with an equally extreme/anomalous 500 mb jet streak that the models indicate will strengthen to around 140 kts over cntl NC through the same time. The SPC Sounding Climo Page indicates winds that strong at that level have only been recorded a handful of times during the period of record at GSO. The related extreme deep layer wind fields will provide for a strongly, mostly- unidirectionally-sheared environment over cntl NC throughout the period. At the surface, a slowly retreating wedge front was analyzed at 10Z across far nrn NC from near ECG wwd to TDF and MWK, then nnwwd to a 999 mb low over WV. A trailing, wavy cold front extended swwd through a pair of 996-998 mb lows over middle TN and nrn AL, then swwd and slightly lagging a srn stream frontal system that delineates the nrn and wrn bound of maritime Tropical air characterized by upr 60s-lwr 70s surface dewpoints and moderate MLCAPE that has surged as far n as cntl AL/GA, swwd to the MS Delta region. The wedge front is likely to become quasi-stationary from nwrn NC newd across cntl VA today, reinforced by periods of widespread rainfall. A growing warm sector, as morning low clouds and areas of rain retreat nwd, will expand across the ern and e-cntl Carolinas through midday to early afternoon, immediately preceding the srn stream/mT front and squall line that will cross the region late this afternoon through early tonight. The slightly lagging frontal zone from WV to middle TN this morning will follow and sweep ewd across cntl NC late tonight and Fri morning. Initially widespread rain this morning is expected to taper off and retreat nwwd into the wrn Piedmont through late morning-midday. Associated boundary layer deepening and mixing southeast of lingering low overcast over the nw Piedmont will cause strong low level winds to mix to the surface and manifest as windy swly surface winds that may gust up to 35-40 mph, strongest from Scotland to Wilson Co. and points sewd. We considered a short-fuse Wind Advisory for those areas from roughly 11 AM to 5 PM, but elected not to issue at this time given that gusts exceeding 40 mph are likely to be isolated. The day shift may elect otherwise should 12Z analyses support slightly stronger warm sector wind. A band of of showers and leading narrow line of intense convection -- with torrential downpours; isolated QLCS/mesovortex tornadoes; and widespread 35-45 kt gusts and isolated higher ones-- will spread east across central NC this afternoon through this evening. While the squall line motion will be ewd, storm motion vectors favor a nwwd cell motion that will favor training and a heightened risk of flooding. Storm total rain amounts are relatively unchanged from previous forecasts, or perhaps slightly less, ranging from 2-4 inches over the Piedmont to 1-3 inches over the Coastal Plain, the latter of which is generally just shy of both 1 and 3-hour Flash Flood Guidance values. As such, no expansion of the FFA will be made at this time. Widespread, trailing "stratiform" rain will likely end within 3-4 hours of the passage of the squall line tonight, along with a lessening of swly surface winds; and this will favor the redevelopment or maintenance of areas of low overcast and fog ahead of the secondary front Fri morning. Scattered showers and even a few storms, owing to markedly cooling temperatures and steepening lapse rates aloft, atop a residually moist and buoyant low level air mass characterized by surface dewpoints in the 50s, will also accompany that secondary front late tonight. Even stronger gradient wind, amidst post-frontal CAA and sharp MSL pressure rises, will likely materialize and spread newd across SC and into at least the wrn half of cntl NC in the few hours prior to 12Z Fri, at which time wind gusts between 35-45 mph will be possible - strongest across the srn Piedmont and Sandhills. A Wind Advisory may be needed for this time period, continuing and expanding ewd into the Coastal Plain early Fri. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... As of 440 AM Thursday... ...Gusty winds with gusts near 40 MPH are expected late Friday morning and early afternoon... The secondary cold front will be moving off the coast by daybreak Friday. The widespread rain and embedded thunderstorms will have moved offshore but scattered showers are still possible during the morning ahead of the approaching upper trough. While the afternoon should be dry in most locations, the vigorous upper trough may be able to squeeze out a shower from the shallow saturated layer atop the boundary layer. Some of the CAMS are suggesting a narrow line of showers the move southeast across central NC during the afternoon. The main story for Friday will be the wind and wind gusts. Cold advection and an impressive pressure field along with decent mixing will support sustained winds of 15 to 25 MPH with gusts of 35 to perhaps 45 MPH during the late morning and early afternoon hours. The strongest gusts will likely occur across the eastern Piedmont, the Sandhills and the Coastal Plain. A wind advisory may be needed. Highs on Friday will range in the upper 50s to lower 60s in most locations, with cooler highs in the mid 50s across the Triad. Dry and chilly conditions are expected on Friday night with lows of 30 to 35. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... As of 440 AM Thursday... An upper level shortwave should will approach and cross the area on Saturday and Saturday night bringing a small threat of some spotty light rain on Saturday afternoon across the Triad and much of the area Saturday night. The system is moisture starved and only light, scattered precipitation is expected. The thermal profile is cold enough such that snow is not out of the question toward the daybreak hours, but have kept the forecast all rain for now given the marginal temperatures. This is supported by SREF forecasts of partial thicknesses near the snow/indeterminate location on the nomogram. Highs on Saturday will range in the upper 40s to lower 50s with lows in the lower to mid 30s on Saturday night. Fair weather is expected for Sunday through early Monday as high pressure extends into the region. A slow moving cold front will approach on Monday and move into the region on Tuesday before a northern stream trough moves across the OH Valley and Mid Atlantic on Wednesday. The result will be a chance of light rain or showers on Tuesday and Wednesday. Highs on Monday will range in the lower to mid 60s and moderate into the 60s to around 70 for Tuesday and Wednesday. -Blaes && .AVIATION /12Z THURSDAY THROUGH MONDAY/... As of 720 AM Thursday... An area of rain and IFR-MVFR conditions and low level wind shear will overspread cntl NC this morning. The steady rain may then end except perhaps at INT/GSO; and this will allow ceilings to gradually lift and scatter within a growing warm sector over the eastern Carolinas through midday to early afternoon, possibly to VFR at FAY and RWI. Associated boundary layer deepening and mixing will cause strong low level winds to mix to the surface and manifest as a windy and gusty southwesterly surface wind. A band of of showers and leading narrow line of intense convection --with torrential downpours; isolated tornadoes; and widespread 35-45 kt gusts and isolated higher ones-- will spread east across central NC this afternoon through this evening. IFR-MVFR conditions will also result at that time. There will be a lull in the rain and lessening of surface winds tonight, at which time areas of low stratus and fog, and redevelopment of low level wind shear conditions, will be possible. Outlook: A secondary cold front will cross the region with scattered showers, a scouring of any preceding low clouds and fog, and following very strong and gusty southwesterly surface winds Fri morning. A passing mid to upper level disturbance and related surface frontal system will cross the region with an associated chance of light rain and MVFR conditions late Sat into early Sun. && .HYDROLOGY... As of 725 AM Thursday... Heavy rainfall remains very likely through tonight, particularly over the NC Piedmont and points westward into the mountains. Increasing deep moisture transport and surging PWs to daily record values, in the presence of strengthening forcing for ascent through the column, will lead to heavy rainfall; and the orientation of convective bands parallel to the steering flow will result in slow movement and higher rainfall amounts. Storm totals of 2-4", locally higher, are expected through tonight from the Triangle west, with 1- 3 " totals in the east. This rainfall over the headwaters of expansive basins will push many mainstem rivers near or over flood stage, including parts of the Dan, Yadkin, Haw, Deep, Rocky, Cape Fear, Neuse, and Tar Rivers and their tributaries. Flashier rivers like the Haw will see quicker response this afternoon and tonight, resulting in a good chance of moderate or greater flooding. While most other sites are currently expected to peak at minor flood, we'll keep a close eye on upstream rainfall as this event unfolds. River flooding may extend well into the weekend over eastern sections, as this rainwater flows through the tributaries and downriver. -GIH && .CLIMATE...
